Abstract

The present invention relates to an improved process for the preparation of nicotinic acids represented by the following structural formula (I): <IMAGE> I which are prepared by reacting a nicotinic amide compound having the formula: <IMAGE> under acidic conditions with a nitrite salt. In the process of the invention have the groups R1, R2, and R3, in the compounds are independently selected from the group consisting of hydrogen, and halogen atoms and R4 is selected from the group consisting of hydrogen, lower alkyl and aryl. The process provides the nicotinic acid compounds in improved yields.
